The Black Sea, with a surface area of approximately 4.2×105 km2 , a volume of 5.3×105 km3 and a maximum depth of @2300 m, constitutes one of the world’s largest in land basins. The Sea borders several different cities and countries. It is an important area for fishing and aquacultures. It receives an enormous quantity of pollutant containing sedimentary material, being fed from all sides by several large rivers and many streams, each of which possesses a large drainage area.
In this work eighteen rivers running to South Eastern Black Sea within the Trabzon region was investigated with regard to some physical and chemical parameters and a pollution map was aimed to be prepared from the obtained data.
Samples have been collected from the points where the rivers reaches to the sea. The eleven investigated parameters are; temperature, pH, sulphate, nitrate, nitrite, phosphate, free chloride, mercury, copper, plumbed and arsenic. The degree of pollution was estimated by the comparison of the obtained data with the standards.
